My current campaign has an aarakocra PC in it - Beaky, a moon druid (4th level). Because it's a forest/swamp hexcrawl, most (but not all) of the challenges take place outside, so he gets to fly around a lot. His chief tactic is to fly over to where enemies are, land, and shift into a bear, tanking for the rest of the party who often fight at range since they're usually dealing with difficult terrain which slows them down from getting into melee. He calls this his "Dropbear Maneuver."
Beaky does occasionally scout out areas of interest to the party prior to them heading in. Most recently he did this to scout out an undead horde so they could figure out a way to deal with this overwhelming force and get at a treasure hoard they wanted. I dropped them on the corresponding map (on Roll20) so they could use the result of Beaky's scouting to determine a plan of attack. Because the party is always dealing with issues relating to the terrain, Beaky's player understands when I tell him that certain things are obscured by trees, swamp gas, clouds of mosquitoes, darkness, heavy rain, or the like.
Beaky also got married (via a shotgun ceremony) to a human female, one of the daughters of a moonshiner who has a caravan park a couple hexes from town. Love is love and we didn't really get into what sort of genitalia he has. Which is not to say that we don't talk about genitalia in my games which are rife with dick jokes, but rather it wasn't important to determining how Beaky "should" be portrayed.
"Hey, so I haven't really been making a deal of the terrain, but I think it will really enhance the strategic and tactical aspect of play, providing you with both challenges to overcome and opportunities to exploit. I'm going to start using it more for determining cover, visibility, movement, and the like. What do you think?"
